The 28-year-old is in his seventh season at Goodison Park and thinks the options available to Roberto Martinez are the best during that spell.
Summer arrivals Gareth Barry, on loan from Manchester City, and James McCarthy, a £13million signing from Wigan, have increased competition in central midfield and the return from injury of Darron Gibson in Saturday's defeat at Manchester City has added to that.
"It is great to see someone of Gibbo's quality back, it just adds to the strength we have in the squad - there is plenty of competition for those places in midfield especially," said Baines.
"That is great for the manager and it gives him the opportunity to rotate sometimes and that is only going to help us."
Asked whether it was the strongest Toffees midfield he had played alongside, he added on evertontv: "From what I can remember it is, just because of the quality we have and there are a lot of players fighting for places.
"We have Steven (Pienaar) to come back (from injury) so if we have everyone back fit we will have a really good squad and the manager has some decisions to make."
While Everton may have lost their unbeaten record at the weekend, they have enjoyed a good start to the season as the squad have embraced the change in style brought by the new boss.
Many predicted a dip in fortunes because of the readjustment period required after Martinez succeeded David Moyes but there has been no evidence of that so far.
"It's a work in progress but we're working towards being a much better team," added Baines.
